Title: Innovations of Narushi Amamoto
Introduction
Narushi Amamoto is a notable inventor based in Fujisawa, Japan. He has made significant contributions to the field of signal measurement technology, holding two patents that showcase his innovative spirit and technical expertise.
Latest Patents
One of his latest patents is the "Burst signal spectrum measuring system with stepwise sweeping." This invention involves a measuring unit that converts a measuring signal into an intermediate frequency band of a predetermined bandwidth. It detects the intermediate frequency band while variably controlling a local oscillation frequency of a local oscillator. A waveform memory is utilized to store the magnitude of a detection signal output from the measuring unit in correspondence with the frequency. An analyzing unit then analyzes the frequency component included in a signal to be measured based on the storage value of the waveform memory. Additionally, an analysis target frequency data setting unit sets frequency data of a desired analysis target frequency or interval frequency data. A sweep control unit changes the reception frequency of the measuring unit into the desired analysis target frequency, outputting an address signal corresponding to the received analysis target frequency to the waveform memory.
Another significant patent is the "Signal analyzer apparatus with automatic frequency measuring function." In this invention, a signal received while a local oscillator is swept in an analog manner is selected and detected by an IF circuit using a desired resolution bandwidth. The resultant data is stored in a memory and displayed on a display unit. A sweep signal generator controls the local oscillator in an analog manner, allowing frequency measurement within a desired measuring frequency range. A peak search section outputs a frequency value corresponding to the maximum value of the data in the memory. A discriminator compares the span set in the sweep signal generator with the resolution bandwidth set in the IF circuit, outputting the obtained value when a frequency is measured. A frequency controller causes the sweep signal generator to perform sweeping and measurement by setting a frequency detected by the peak search as a center frequency.
